pub unsafe static NSWindowDidChangeOcclusionStateNotification: &'static NSNotificationNameAvailable on crate feature
NSWindow only.Expand description
Upon receiving this notification, you can query the
NSWindowfor its current occlusion state. Note that this only notifies about changes in the state of the occlusion, not when the occlusion region changes. You can use this notification to increase responsiveness and save power, by halting any expensive calculations that the user can not see.
